Perpetual calendar - Once set, the
calendar automatically adjusts for odd and
even months including February of leap years
up to February 28, 2100.

Automatic kinetic power generator -
powered by the motion of your wrist.

When the watch senses 24 hours of
inactivity it puts itself into suspended
animation (sleep mode) to conserve energy.
The date continues to advance correctly
while the watch is asleep. Wake it up with a
few shakes of your wrist and it
automatically resets itself to the correct
time even if it's been asleep for up to four
years.
